## Trust breakdown

How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

Scored 2026-11-05.

- **Supply Chain Security**: 100/100
  - No malware found by supply-chain analysis.
  - No known CVEs affecting this package version or its production dependencies.
  - No install/post-install scripts declared.
  - No production dependencies, so there is no dependency health to assess.
- **Provenance & Transparency**: 97/100
  - Source repository is publicly reachable at the declared URL.
  - Cryptographically verified build provenance (signed, bound to pipeworx-io/mcp-overheid-nl).
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 1 days ago).
  - Disclosure check failed: no security disclosure policy was found in the source repository.
- **Schema Quality & AI Usability**: 76/100
  - AI-judged instruction clarity (good).
  - Tool/resource definitions use about 456 tokens (~114/item across 4 items; 4 tools + 0 resources), lean.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 0/100
  - Stability not yet verified: not enough scan history yet (needs a 30-day window).
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 4 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 5 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

**Unverified: 1 category.** A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

First indexed and scored.

## MCP tools (4)

### `search_datasets` (~165 tokens)

Search the data.overheid.nl catalogue of Dutch government open data (CKAN package_search). Returns matching datasets with titles/descriptions (mostly Dutch). Query may be Dutch or English; Dutch matches more.

Input parameters:

- `fq` (string): Solr filter query, e.g. "organization:cbs-microdata" or "tags:onderwijs".
- `query` (string, required): Search terms, Dutch or English. e.g. "onderwijs", "verkeer", "health", "budget". Use "*:*" to match everything.
- `rows` (number): Max results, 1-1000 (default 25).
- `sort` (string): Sort spec, e.g. "metadata_modified desc".
- `start` (number): 0-based offset for paging.

### `dataset_details` (~94 tokens)

Full dataset record by id or slug (CKAN package_show), including its resources. Each resource has a download "url" and "format" (CSV/JSON/etc.) — the portal is metadata-only, so fetch those URLs to get the actual data.

Input parameters:

- `id` (string, required): Dataset id or slug, e.g. "leerlingen-speciaal-onderwijs-per-samenwerkingsverband-primair-onderwijs".

### `list_organizations` (~73 tokens)

List publishing organizations (ministries/agencies/provinces) on data.overheid.nl (CKAN organization_list). Use an org "name" in search_datasets fq, e.g. "organization:<name>".

Input parameters:

- `limit` (number): Max orgs, 1-1000 (default 100).

### `list_groups` (~69 tokens)

List thematic groups/categories on data.overheid.nl (CKAN group_list). Note: this portal currently exposes no groups (returns an empty list) — prefer fq facets on search_datasets to narrow by theme.

Input parameters:

- `limit` (number): Max groups, 1-1000 (default 100).

## Common questions

### What is the Overheid Nl MCP server?

Overheid Nl is an MCP server listed in the public MCP registry as io.github.pipeworx-io/overheid-nl. data.overheid.nl MCP, the Netherlands national open-data portal (CKAN API). This page covers its npm package (@pipeworx/mcp-overheid-nl).

### Is the Overheid Nl MCP server safe to use?

Overheid Nl scores 81 out of 100 on VerifyMCP. We found no known CVEs affecting it as of 5 November 2026. It declares no install or post-install scripts. Its build provenance is signed and verified. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### What tools does the Overheid Nl MCP server expose?

Overheid Nl exposes 4 tools: search_datasets, dataset_details, list_organizations, list_groups. Their descriptions and schemas cost roughly 401 tokens of context every time the server is loaded.

### Is the Overheid Nl MCP server still maintained?

Overheid Nl is still listed as active in the MCP registry. We last reached this channel on 5 November 2026. Those dates come from our own scans of the registry and the channel itself, not from anything the publisher announced.

### What licence is the Overheid Nl MCP server under?

Overheid Nl declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.

### What did VerifyMCP test on the Overheid Nl MCP server?

VerifyMCP ran 15 checks on Overheid Nl, covering Malware scan, Known CVEs, Install scripts, Dependency health and 11 more. One item could not be completed, a gap on our side rather than a finding about Overheid Nl: Stability. One category scores 0 for that reason, because we only credit what we can confirm. Endpoint Security and Transport & Reachability do not apply to an npm package, so they were not tested. The score does not measure everything, and the scoring documentation lists what it leaves out.
